WASHINGTON, May 15, 2015 /PRNewswire-USNewswire/ -- NASA has opened media accreditation for the New Horizons spacecraft's historic encounter with Pluto in mid-July.
WASHINGTON, May 12, 2015 /PRNewswire-USNewswire/ -- NASA laboratory experiments suggest the dark material coating some geological features of Jupiter's moon Europa is likely sea salt from a
A newly-released image of Europa captured by NASA’s Galileo spacecraft shows a portion of the Jovian moon’s crust known as Conamara Chaos that is marked by long grooves etched into its shattered chunks of ice and which criss-cross along the surface.
Researchers have for the first time captured detailed images of heat rising from the horseshoe-shaped lava lake on Io, the innermost moon of Jupiter. Cool!
It's confusing, we know. But we have the answer. At least by astronomer standards.
New images captured by NASA’s New Horizons spacecraft have revealed a bright feature near the visible pole of the dwarf planet Pluto – a feature that could be a polar cap made out of frozen molecular nitrogen ice, officials from the US space agency announced on Wednesday.
WASHINGTON, April 29, 2015 /PRNewswire-USNewswire/ -- For the first time, images from NASA's New Horizons spacecraft are revealing bright and dark regions on the surface of faraway Pluto - the
If this image gives you the heebie jeebies, you might not want to wait around for New Horizons to get a good look at the spider-like patterns on Pluto.
WASHINGTON, April 14, 2015 /PRNewswire-USNewswire/ -- NASA's New Horizons spacecraft is three months from returning to humanity the first-ever close up images and scientific observations of
Geologists from the University of Maryland have uncovered new evidence supporting the belief that the moon formed after a roughly Mars-sized body struck and merged with Earth, causing the formation of a large debris cloud that ultimately coalesced and formed our satellite.
Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...
Saturn's moon Hyperion -- Hyperion is a moon of Saturn discovered by Bond and Lassell in 1848. It is the largest highly irregular (non-spherical) body in the solar system (Proteus is quite a bit larger but is almost spherical). It seems likely that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past. The largest crater on its surface is approximately 120 kilometers in diameter and 10 kilometers deep. Like most of Saturn's moons, Hyperion's low...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
Jupiter's Moon Europa -- Europa is a puzzle. The sixth largest moon in our Solar System, Europa confounds and intrigues scientists. Few bodies in the Solar System have attracted as much scientific attention as this moon of Jupiter because of its possible subsurface ocean of water. The more we learn about this icy moon, the more questions we have. Because the nature of science is to ask questions, we cannot resist the mystery of Europa and its potential for possessing an ocean. Early...
